After the events that unfurled in part 1, our sex life took on a new intensity we hadn't had since the early days. Sam's sexual appetite grew and grew into something like I always dreamed it would, and our sex was much more wild and dirty. No longer did she give my cock a few licks, oh no, now she sucked me dry, actually enjoying every mouthful of cum I could give her.
What we both vocalised during our fuck sessions, was the excitement we felt that first threesome with Charles, and while we hadn't repeated it, I think we both knew that it was only the first of many such steamy adventures.
One thing I couldn't get Sam to let me do to her was take her virgin arse, something completely taboo before her 'change', but now something that got me a rueful smile when I brought it up now. "Come on Sam, you know how much you enjoyed feeling Charles' tongue rimming you, just imagine that but tenfold more, as my cock slides into you," I reasoned, trying to persuade her how much fun she was missing out of. Of course to help my words I was laying behind her, our sweaty bodies melded together, my hardening cock nestling between her soft arse cheeks, the fingers of my right hand slowly pleasuring her clit, rubbing up and down her soaking wet slit.
"Mmmm, I know, it did feel so good. I'm just not sure I'm ready to take a cock there," She reasoned, pushing back against my hardness as she rotated her hips. "Maybe I just need someone to break me in when I really am letting go?" she breathlessly hinted, body trembling, waiting for my reaction.
I had to stifle a laugh, here was my own wife trying to blackmail me into letting her fuck another man again, and fuck her up her tight arse at that. Well I was more than happy to give into her demands, being something I wanted to happen again as soon as possible. "You bad girl!" I played along, "You want to let another man fuck you up your tight little arsehole don't you slut? You want to be nasty with another man?" I teased, my fingers rubbing her swollen sensitive clit faster as my words had their effect.
"Yes… yes!" Sam cried, her pent up excitement building with every stroke of my finger, with every word I whispered into her ear.
"You're going to let him force his hard cock up inside your hot red raw hole, until he fills you with cum, while I watch, watch you let him fuck you like an animal," I cry, my own excitement getting the better of me, as I rubbed my aching cock up and down between Sam's grinding arse, pre-cum coating her arse cheeks, making her skin slippery for me to fuck.
Sam pushed her own hand to join mine playing at her pussy, stuffing fingers up herself as I keep circling her clit, her body lost to the sensations, and her eyes closed, imagining the scene of her first anal fuck, a taboo fuck with her husband watching. All the while my cock rubbing against the rosebud of her anus must have helped add to the sensations, my own cock slick with pre-cum and sweat, rubbing up and down, faster and faster.
I lost myself in the fantasy, rubbing my cock against her, our entwined fingers now roughly rubbing her cunt as her orgasm took hold. Knowing that she was cumming imagining sex with another man drove me past the edge, and as Sam's body shook in my arms, my own orgasm hit, my cock spewing cum over her arse, my cock grinding it over her right hole, and up over her lower back.
We laid together in our sticky mess for several minutes, getting our breath back and wondering if the other really wanted the fantasy to become reality again, or was it just something used to get the other off?
Sam broke the silence first, throwing me completely with her change in direction. "Come to the gym with me tomorrow night?" she asked me, propping herself up looking up into my eyes.
"Oh come on, you know that place bores me," I complained, a little off put that Sam was moving the conversation into such a mundane topic.
"Oh I don't know, I think you might be surprised," Sam answered me, a devilish smile touching her eyes.
"Hello, what's this, what haven't you been telling me?" I was intrigued; maybe Sam wasn't changing the topic of conversion as much as I feared.
"Promise not to get mad? Well, there's a guy there who's been making it obvious he's wanted me for some time. He's a bit of a jerk, but he does have a great body. I've obviously been putting him off, but now, well, I thought maybe I could have some fun?"
I looked down at my long time partner, and new time slut, I couldn't hide my excited smile. "I think you're right, I better come along and work out tomorrow."
That next day work dragged, as I sat at my computer daydreaming, hoping that something special would happen again that evening. The only break in the monotony was an e-mail from my dear wife, telling me how naughty she felt, and that she couldn't wait to see my face when another man had his hands on her body again. Needless to say I had a big stupid grin on my face the rest of the afternoon after that.
Early evening was spent at home eating a light meal and idly chatting about our respective days. Sam normally went to the gym late evening, when it was quiet after the 'after work rush' as she called it. I found out that the guy in question's name was Steve, after I managed to get her to admit that she had talked to him before, just never let his flirting go any further. She told me that he usually was at the gym all hours, and seemed to be there whenever she was on one of her late sessions. She laughed when I suggested it might have been no co-incidence, maybe he was there to watch her get hot and sweaty.
Once we reached the gym, we agreed that we would split up, so no one could tell that we were a married couple. Normally the gym bored me rotten, but that night it took on a whole new excitement. I tried to keep an eye on my semi clothed wife, her bodies curves accentuated under her tight body suit, her face flushed red with the effort on the exercise machines. We had been there nearly an hour, and I had almost given up hope of anything happening that night, when I noticed that Sam was chatting to a man who was helping her while she did her chest curls. I knew why that had got his attention, as the exercise was making Sam's large firm breasts stand out even more, the material of her top straining to contain them. I moved around closer, so I could try and make out what they were saying. If this was 'Steve', he was just what I expected from someone who spent all their time in a gym, a blond haired man who was all body. Not someone that Sam would normally give the time of day, but I could see why she'd pick him for a moment of pure sex.
From what I could pick out, their conversation was mainly about exercise, nothing to get excited about. I wouldn't have known that this Steve was interested if it wasn't for the glances I saw him make down at my wife when he thought she wasn't watching. I wondered if Sam could feel his eyes on her body, feeling them slide down from her breasts to her lycra clad groin.
Sam did seem to spend more time on that last piece of machinery than any other, and as they chatted her smiles became warmer and more coy, and his glances become longer lustful stares, Sam catching him several times, obviously enjoying the attention. While helping her set the weight, I could see his hands accidentally touch her, and when it becaome obvious to him she wasn't resisting, his accidents become more frequent and obvious, lingering touches on her legs, arms, and more than once sliding lightly across her breasts.
Before things went any further, I was disappointed when he left her, taking his towel and heading back to the men's changing rooms. Sam watched him go, making sure he'd left before running to join me.
"I think he's interested, don't you Chris?" she smugly whispered to me, tracing her finger over the bulge in my shorts. "He's got me all wet with his touches, that naughty man. I told him I was married, but he couldn't keep his hands off me."
"Sounds perfect," I laughed. "So why did you stop?"
"Oh we've not, I'm meeting him in the sauna in ten minutes. So if you want to keep an eye on me you better get in there quick." Luckily my wife was already playing the slut role so well, so with a wink I rushed off to get changed for the sauna, hoping to get myself in there well before Sam and her new man.
I'd forgotten how hot those damn things were I thought to myself as I entered the hot humid sauna. As it was getting late, I found it completely empty, so took up a seat in the far corner, wrapped in a large towel, with my leg up so that my cock could have the room to get hard without notice.
I poured more water onto the coals, sending clouds of hot steam into the air, almost helping hide me, and breathing deeply I settled back for the show.
